Property 'get' does not exist on type 'GoogleMapsMarker'


I am using cordova-plugin-googlemaps for native map support in Ionic2(typescript). According to their documents, I can save custom attribute in marker object then retrieve it using marker.get(). But I am getting this error
"Property ‘get’ does not exist on type ‘GoogleMapsMarker’".
I posted this issue to cordova-plugin-googlemaps community. They replied this support has been removed from Ionic2 wrapper. Now how to solve this issue.
